Q:
If I have 1600 gems and I want to exchange it to gold, the current value of the gems, for example, is 100 gems -> 100g. I would assume that when I make the exchange, the value of gems will drop, thus when I expect a 1600g from 1600gems, I’ll actually receive something lower.
For example, if the value of gems drops by 1% per 100 gems, then instead of 1600g, I’ll receive ~1480g. That is assuming a 1% drop per 100 gems.
Thank you for your time.

The reason I say it does change because there have been times when I click buy that the amount of gems I can get goes down by one. Of course there could be hundreds of other buyers and sellers executing transactions around the same time.
If you play with the amount of gold you are willing to sell with the mouse wheel you will see that the rate does change while you are on the screen and it doesn’t seem periodic in time, like every 15 seconds so transactions could be batched. If the price changes to much from the time you enter the amount of gold/gems you are willing to trade I’ve had the transaction “fail”. JS has mentioned that the exchange will only take what’s actually needed in gold to give you X gems so you can’t be overcharged. Example, if you enter 3g and it says you will get 22 gems, those 22 gems may only cost 2g90s so that’s all the exchange takes out of your bank.
As a matter of fact JS just answered something about the calculation for the exchange and how it processes requests. You may be disappointed by the answer.

It goes both ways. Because the Gem Exchange ratio changes with each transaction, you could get less or more, depending on your timing. For example, say Anet has a huge sale in the Gem Store, and there’s some epic new gear. Players who are online at that moment, worldwide, all start exchanging Gold → Gems. If you’re online at the same moment that everyone else is exchanging, you could see 100 Gold for 10 Gems on your screen, but when you click the button, you could end up with only 8 Gems.
The exchange rate is calculated using the amount of gold and gems are currently in the exchange. If it’s a simple ratio or a more complex relationship, we don’t know, that’s all John Smith has told us. He also told us the the exchange was set up with an initial small amount of gold and a massive amount of gems. So as gold is exchanged for gems, gems become worth more. When gems are exchanged for gold, gems are worth less.
It does appear that the rate is recalculated after each exchange. Also the Gem to Gold rate is 72.25% of the Gold to Gem rate. Since 72.25% is 85% squared it’s believed that the exchange sinks 15% of the gold when it enters or leaves the exchange.
This link will show you how much the rate changes throughout the day/week/month and since the game started.

Yes, that’s exactly what I want to know. At what point does the worth of gem fluctuates? Is it every 100 gems exchange? Is it per single gem? Or is it time based where it calculates after 3 minutes?
It does appear that the rate is recalculated after each exchange.
If that is the case, then the exchange viewer is not real time. Also if that is the case, then the exchange is making calculation every microsecond to handle the amount of transactions going on within a given minute. Thus I doubt that would be the case.
It is more likely that they freeze the rate for X amount of gems, then recalculate. For example, they recalculate for every 100 gems exchange.
Thus from my example at the OP, a 1600 gems exchange will yield ~1480gold if the starting rate is 1:1 and drops 1% per 100 gems.
Or they freeze the rate for X amount of time, then recalculate. For example, they recalculate after 1 minute.
Thus it is a guaranteed 1:1 rate for the whole 1 minute and I will get 1600gold for my gems if traded within that time frame.
Can you point me to the post where John Smith talk about the exchange rate? Thanks.

This is actually the answer I’m looking for. Thank you.
